National Football League telecasts topped the rankings of C3 commercial ratings among persons 18-49 in the first week of the new TV season, according to data released today by The Nielsen Company.

The NFL claimed the top four spots in the rankings for C3, which measures the commercials watched both live and with three days of DVR playback. C3 is commonly known as the metric under which much of primetime advertising is bought and sold.

ABC's "Grey's Anatomy" is the first non-sports telecast to appear on the list, coming in at #5 for the week with a 5.1 C3 rating among persons 18-49. The show's C3 rating was 30% higher than its live-only commercial rating. On average, the C3 rating for the top 20 shows on this list was 8% higher than its live-only commercial rating.

CBS's "Hawaii Five-O" and "$#*! My Dad Says" were the season's only two new shows to crack the top 20 in the first week. Each show's C3 rating was 0.6 points higher than its live-only commercial rating
